Database Programming Using VB 6.0 (Part Three)
Data Environment Designer
These are the steps to connect VB 6.0 with MS SQL server database using Data Environment Designer method. Data Environment Designer also helps us to generate a report using Data Report control.
Database Programming Using VB 6.0 (Part Two)
ActiveX Data Object (ADO) Control Method
These are the steps to connect the VB 6.0 with MS SQL server using ADO control:
-
Activate the Microsoft ADO control and Data Grid control 6.0 from the ActiveX components. ADO and Data Grid Control icons will become part of toolbox after activation.
Database Programming Using VB 6.0 (Part One)
There are five main methods to connect the database using VB 6.0. VB 6.0 can be connected with all popular relational databases, such as Oracle, Microsoft Access and SQL servers.
- Data Control.
- ActiveX Data Object (ADO) Control.
- Data Environment Designer.
- Data Wizard.
- Open Database Connectivity (ODBC).
Menu Programming and Multiple Form Programming Using VB 6.0
Menu Programming Using VB 6.0
A menu is a collection of commands under a single term, such as File and Edit menus. VB 6.0 allows programmer to develop menus according to the requirements of applications.
These are the steps to develop menus:
Repetition Programming and Function Procedure Programming Using VB 6.0
Repetition Programming Using VB 6.0
Repetition programming structure is used to repeat the same piece of code again and again without rewriting it. Repetition structure is also called iterative or looping structure. There are four steps to use loop structure:
Selection Programming and Sub Procedure Programming Using VB 6.0
Selection Programming Using VB 6.0
Selection is a method of writing programs to choose between two or among different things, such as to select a job opportunity offer from two different organizations. If-then-else structure is used for selection programming. Relational operators are used for comparison among different things, such as greater than and less than.
Sequence Programming Using VB 6.0
Sequence is a method of writing programs in a particular order, such as a driver of a car performs actions in a sequence to drive a car. VB 6.0 supports arithmetic operators like C and C++ programming languages.
Fundamentals of VB 6.0 Programming and Programming to Display a String
Fundamentals of VB 6.0 Programming
VB 6.0 helps a programmer to develop and execute event driven programming applications without developing any additional programs, such as editor, compiler, interpreter, textbox, label box and command button. Programmers write codes against events. These events are called click event.
VB 6.0 Programming and Integrated Development Environment of VB 6.0
VB 6.0 Programming
Visual Basic (VB) was evolved from the BASIC (Deitel & Deitel 1999). BASIC stands for "Beginner’s All Purpose Symbolic Instruction Code". Microsoft Corporation introduced VB in the late 1980s and in early 1990s as Microsoft Graphical User Interface evolved. VB 6.0 is the sixth version of VB as the name is indicating. VB.NET is the seventh version. VB 6.0 provides an integrated development environment (IDE). IDE allows a programmer to develop rapid applications and prototypes. Programmer does not need additional programs to run, debug and develop applications using VB 6.0. IDE is built from controls. Controls are reusable predefined components. VB 6.0 is the most widely used tool to develop rapid applications. VB 6.0 is available in three editions:
Programming of Arithmetic Operators and Predicates and Programming to use Append Using Structures
Programming of Arithmetic Operators and Predicates
Prolog is used to develop Information Systems other than the Expert Systems. Therefore, it supports the arithmetic operators like procedural programming languages, such as C, C++ and JAVA. Common arithmetic operators are as follows:
